(GOLF TEE.

10 alt whom-it may concern:

Be it known that 1, JOHN W. SIBBALD, a subject of theKing of Great Britain, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in' Golf Tees, of which the following is a specification.

The invention relates to an improved golf ball tee which a player may conveniently carry with him and by whichhe may ad ust the height of the ball to suit the requirements. The invention has for its object to provide'a device of this character which shall be light and readily portable and wherein the adjustable holder will be so constructed that it may not be detached from the base of the tee and, therefore, cannot be lost. A still further object of the invention, consists in the provision of means whereby the adjustable portion will be selfcleaning and thereby prevent same from sticking or, becoming clogged with dirt or other foreign material.

The nature of the invention, however, will best be understood when described in 'connection with the accompanying drawings, 1n

' Which- Fig. 1 is a planview of the improved tee.

Fig. 2 is a vertical sectiontaken therethrough on the line 22, Fig. 1.

Figs. 3 and 4, are detail views of the adjustable ball support, Fig. B'being a plan thereof, and Fig. 3: an elevation.

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, 10 designates a circular skeleton base, preferably, from a portion of which a segment has been removed leaving a clearance space 11; and it is also preferred to bevel the edge of the material at this clearance space so that in case a club should strike the base, the blow would tend to be deflected upwardly. At the central portion of the base, there is provided a conical hollow boss 12, which is pro vided with internal threads 13; and there is designed to fit said conical boss a ball support member 14. her 14 is provided with a number of threads 15 adapted to iengage the threaded portion of the boss 13 and thereby to be adjustable vertically thereof.

In order to prevent withdrawal and possible loss of the said ball holding menber,

the-upper outer end 16 of same is u set or wardly "directed shoulder 17 to form an abutment for the threads 15- andrthus prevent withdrawal of the ball holder in the opposite direction' Moreover, I have found by providing longitudinal slots 18 in the; periphery of the ball holder, that any dirt or foreign matter which might accumulate in the boss will be readily removed in the rotation of said member through the the grooves.

The outer end of the member 14:, moreover, is provided with a semi-spherical recess or cavity 19 to'retain a ball (not shown) and the height of same above the ground may be adjusted to suit by rotating the member 14 accordingly.
